Google 應用內購買始終會獲得退款

Question

我對谷歌應用內購買有一些問題。 所有收到的款項將在 72 小時后退還。 我的付款代碼有錯誤嗎？ 我自己付了錢，沒有要求任何退款，但即使是在 72 小時后退款。

    mBillingClient = BillingClient.newBuilder(MainActivity.this).setListener(this).enablePendingPurchases().build();
    mBillingClient.startConnection(new BillingClientStateListener() {

您似乎沒有正確確認購買。

如果您使用 Google Play 結算庫 2.0 或更高版本，您必須在三天內確認所有購買。 未能正確確認購買會導致這些購買被退款。

您可以在文檔中找到更多詳細信息： https://developer.android.com/google/play/billing/billing_library_overview#acknowledge

BillingClient client = ...
AcknowledgePurchaseResponseListener acknowledgePurchaseResponseListener = ...

void handlePurchase(Purchase purchase) {
    if (purchase.getPurchaseState() == PurchaseState.PURCHASED) {
        // Grant entitlement to the user.
        ...

        // Acknowledge the purchase if it hasn't already been acknowledged.
        if (!purchase.isAcknowledged()) {
            AcknowledgePurchaseParams acknowledgePurchaseParams =
                AcknowledgePurchaseParams.newBuilder()
                    .setPurchaseToken(purchase.getPurchaseToken())
                    .build();
            client.acknowledgePurchase(acknowledgePurchaseParams, acknowledgePurchaseResponseListener);
        }
    }
}
